Tilling Tips & Techniques

Let the tiller do the work

•While tilling, relax and let the wheels pull the tiller along while the tines do the digging. Walk on the side that is not yet finished (to avoid making foot- prints in the freshly tilled soil) and lightly, but securely grip the handlebar with just one hand. See Figure 4-2.

•Avoid the temptation to push down on the handlebars in an attempt to force the tiller to dig deeper. Doing so takes the weight off the powered wheels, causing them to lose traction. Without the wheels helping to hold the tiller back, the tines will attempt to propel the tiller backward toward the operator– often causing the tiller to skip rapidly across the ground.

Tilling depths

•When preparing the soil, till a fresh path on each pass rather than overlap- ping passes. This gives the wheels maximum traction on undisturbed soil. See Figure 4-6. Dig as deeply as possible on each pass without over- loading the engine. Later passes can be overlapped. (Watering the garden area a few days prior to tilling will make tilling easier, as will letting the newly worked soil set for a day or two before making a final, deep tilling pass.)

•When cultivating (breaking up the surface soil around plants to help destroy weeds), adjust the tines to dig only 1-1/2" to 2" deep. Using shallow tilling depths helps prevent injury to plants whose roots often grow close to the surface. If needed, lift up on the handlebars slightly to prevent the tines from digging too deeply. Cultivating on a regular basis not only eliminates weeds, it also loosens and aerates the soil for better moisture absorption and faster plant growth.

Avoid tilling soggy, wet soil

Tilling wet soil often results in large, hard clumps of soil that can interfere with planting. If time permits, wait a day or two after heavy rains to allow the soil to dry before tilling. Test soil by squeezing it into a ball. If it compresses too easily, it is too wet to till.

Avoid making footprints

Whenever possible, walk on the untilled side of the unit to avoid making foot- prints in your freshly tilled or cultivated soil. Footprints cause soil compaction that can hamper root penetration and contribute to soil erosion. They can also “plant” unwanted weed seeds back into the freshly tilled ground.

Choosing correct wheel and tine speeds

With experience, you will find the “just right” tilling depth and tilling speed combination that is best for your garden.

Set the engine throttle lever at a high enough speed to give the engine adequate power and yet allow it to operate without overloading it. Fastest engine speeds may be desirable when making final passes through the seedbed or when cultivating. Selection of the correct engine speed, in relation to the tilling depth, will ensure a suffi- cient power level to do the job without causing the engine to labor.

Suggested tilling patterns

•When preparing a seedbed, go over the same path twice in the first row, then make individual passes right next to each other (see Figure 4-6). When finished in one direction, make second passes at a right angle as shown in Figure 4-7.

In very hard ground it may take three or four overlapping passes to thor- oughly pulverize the soil. (See Figure 4-8.)

•If the garden size will not permit lengthwise and then crosswise tilling, then overlap the first passes by one- half a tiller width, followed by succes- sive passes at one-quarter width (see Figure 4-8).

•With planning, you can allow enough room between rows to cultivate (see Figure 4-9). Leave room for the hood width, plus enough extra room for future plant growth.
